The reader reads multiple tags for a specified period. At the end of the specified period, it returns read results
to the host and then it begins the next transaction until termination command has been sent. At each period,
the reader returns all read tag’s results to the host. If it does not read any tag during each time period, it returns
response meaning there is no tag.
